Provided is a semiconductor device in which generation of a parasitic channel in an end region of an oxide semiconductor film is suppressed. The semiconductor device includes a gate electrode, an oxide semiconductor film, a source electrode and a drain electrode, and a channel region formed in the oxide semiconductor film. The channel region is formed between a first side surface of the source electrode and a second side surface of the drain electrode opposite to the first side surface. The oxide semiconductor film has an end region which does not overlap with the gate electrode. The end region which does not overlap with the gate electrode is positioned between a first region that is the nearest to one end of the first side surface and a second region that is the nearest to one end of the second side surface.
